simple dog psycology.
I am the biggest fish in the tank, no one comes near me unless they want a beating
I also have a giant gourmai that is 1.5 feet long, I had to slap here in the fac e twice before she learnt that I am the big fish.
My arowana, I had to scare once, and now he knows
When I'm in the tank, everybody hides, and I don't get bitten
